portions of the slots in which the guide swings or flanges of the upper sash operate. These slots are normally open and communicate with the interior of the hollow terior of a window structure'of the above type, showing the novel closure in place and one side of the frame being illustrated in section.

metal window-frame is employed. This includes vertical side members 5, having outer walls 6 and inner walls, the latter including a section 7, a removable section 8, and an inner section 9. The section 8, as clearly shown in Figure 3, terminates short of the sections 7 and 9, thereby producing longi tudinal guide slots 10 and 11. The slots 10 are for the inner sash, designated generally by the reference numeral 12. The slots 11 are for the outer sash, designated 13. The inner sash 12 is provided with outstanding guide flanges or wings let that operate in the slots 10. The outer sash is provided with In the embodiment disclosed, a hollow corresponding guide wings or that operate in the slots 11. T 1 Now, it will be evident that with the ordi-. nary structure, when the sash13 is in its uppermost or closed position, the portions of the slots 11 beneath it afford communication between the outside atmosphere and the interior of the side members '5 of the Twindow-frame. The present invention while ad dressed particularly to the closing off of such communication for these. portions of the slots, is'obviously not limited to thoseparticular portions, but the invention may be employed in any or all portionsofthe said slots.

In the present embodiment closure "mem bers are employed, each of which preferably comprises a spring bronze sheet or strip bent into trough-form and substantially U or V- shaped in cross section. That is to say,each strip consists of a relatively narrow rear wall 16 with divergent side walls 17. These side walls terminate at their free margins in outturned flanges 18 and the walls adjacent to the flanges are furthermore longitudinally beaded as shown at 19, so that said beads with the flanges define channels 20 in the outer sides of the said side walls 17. The strips or members are long enough, as shown in Fig ures 1 and 2 toextend the full length of the portions of the open slots beneath the outer flanges, 15

or upper sash 13 and slightly overlap the guide wings or flanges 15... Theirear walls16 1 edges constitute the side walls of the slots '11, I

will engage in the channels 20. The walls 17 of the closure members are wide enough sothat asclearly': shown. in: Figure 3,"the

guide flange that projects through the-slot and said guide flange can move freely up and 'member will surround the portion of the frame wall sections 7 and 8,1nay be rovided with openings 21 who-receive suitable asteriersr slot and a sash having a guide slidably en- It will be evident that these members when in place in the normally exposed portions of the guide slots, close the'same against the entrance of air into the interior of the window frame. They are readily insertible and removable and do not require material modification of the window frame structure.

From the foregoing, it is thought that the construction, operation and many advantages of the herein described invention will be apparent to those skilled in the art without further description and it will be understood that various changes in the size, shape, proportion and minor details of construction may be resorted to without departing from the spirit'or sacrificing any of the advanta es of the invention.

what I claim is V V 1. In combination with a hollow window frame having a wall provided with a guide gaged in the slot, of a trough-shaped weather shield forming a closed channel behind the slotand embracing'the portion of the guide engaged therein, and having its opposite sides engaged in the slot on opposite sides of the guide therein; e

2. Incombination with a window frame including an inner side wall having a guide slot, and a sash having a guide flange slidable in the slot, of a channeled member insertible through the slot from'the exposed side of the wall and extending around the rear portion of the guide flange engaged in the slot, the free margins of the sides of the members being engaged in the slot on opposite sides of the guide flange.

3. In combination with a window frame including an inner side wall having guide slot, and a sash having a guide flange slidable in the slot, of a" channeled member insertible through the slot from the exposed side of the wall and having side walls engaged with the walls of the slot on opposite sides of the guide flange, said channeled member extending around the rear portion of the guide'flange engaged in the slot.

4.- Incombination with a window frame includingan inner side wall having a guide slot, and a sash having a guide flange sli-dable in, the slot, of a channeled member having its closed side insertible through the slot from the exposed side of the wall and have ing side walls provided with means that interfit with the walls of the slot to position the channeled member, said member extend ing around the rear portion of the guide flange engaged inthe slot. 7 7

f5. Incombination with a window frame including'an inner side wall havinga guide slot, and a sash'having a guide flange slid .ablein the slot, of a channeled member in sertible through the slot from the exposed 7 side of the wall andhavingsidewalls provided with outwardlyribbed portions that embrace the walls of the slot on opposite sides rear portion of the guide flange engaged in the slot.

6. In combinationwith a hollow metal window frame having inner side walls provided with longitudinal guide slots and a sash movable in the window frame and having guide flanges extending into and slidable in said slots, of channeled slotclosures extending behind and across the slots around the guide flanges, and each having side walls on opposite sides of the flanges engaged in the slot of the side wall,

7. In combination with a hollow metal window frame having inner side walls provided with longitudinal guide slots, and a sash movable in the Window frame and having guide flanges extending into and slidable in said slots, of channeled slot closures fitted longitudinally into the slots and extending into the window frame, said closures surrounding the portions of the guide flanges that extend through the slots, and having portions engaged with the walls of the, slots on opposite sides of the guide flanges therein.

8. A slot closure for metal window frames comprising an elongated channeled strip of i a width to enter and be seated in the guide slot of a metal window frame and surround the guide flange of a sash engaged in said slot, said strip having'a rear wall and side walls, the latter having means for embracing the edges of the window frame wall that are on opposite sides of the slot.
